Merge branch 'claude/ecstatic-elgamal'

- Add missing-data warning when reserve_components table is empty so
  users see "No reserve components found" on the dashboard
- Change AI prompt to show "N/A" instead of "0.0%" for funded ratio
  when no components exist, preventing misleading "0% funded" reports
- Instruct AI not to report 0% funded when data is simply missing
